The Twins acquired the 25-year-old from the Mariners last July in exchange for Kendrys Morales. Pryor, who underwent surgery to repair his latissimus dorsi muscle in 2013, excelled at Triple-A for the Twins after the trade recording a 0.89 ERA and 9.7 K/9 in 14 relief appearances covering 20 1/3 innings, but demonstrated a lack of command as evidenced by his 7.1 BB/9 rate.
